' LOCK DEVICE FOR SHADE ROLLERS.

Application filed November 23, 1920. Serial No. 425,976. Renewed July 2, 1923.

- pertains to make and use the same.

This invention relates to means" for supporting shaderollers in position in a window frame and for locking the same against accidental displacement therein, and the object of the invention is to provide a device of this class which is simple in construction and operation and eflicient in use, and which is constructed as hereinafter described and claimed;

The invention described and claimed herein isan improvement on that described and claimed in afprior patent granted to me August 14,1917, No. 1,236,393, and the invention is fully disclosed in the following 2 specification, of which the accompanying drawing forms a part, in which the separate parts of my improvement are designated by suitable reference charoters in each of the views, and in which V Fig. 1 is an insideview of the top portion of a window frame and indicating one use of my improved lock device; I

Fig, 8 a partial section on the 'line '8 '8 of Fig. 2 and showinga modification,

In Fig. lot the drawing I have indicated at 10 the top portion of a window frame and at 11 the side portions of said frame between which a shade roller 12 is mounted. The shank 13 at one end of the shade roller is mounted in a suitable keeper .60 14 while the shank 15 on the other end of said roller is mounted. in one of my improved lock devices 16. j v The lock device 16 comprises a suitable casing 17 which, in the form of construction shown, is oblong and rectangular in general form and comprises a front plate 18 and inwardly directed side plates 19 forming a chamber 20. The upper end of the front plate 18 is provided with an aperture 21 which opens upwardly therethrough. The side plates 19 are provided adjacent to theupperend thereof with laterally direct: ed ears 22 through which nails, screws or similar devices23 are passed'into, the side members 11 of the window frame in securing the casing 17 in position.

A spring member 24 is mounted within thecasing 17 and between said casing and side member '11 of the window frame, said spring member comprising an enlarged head portion 25 having apertures 26 through which the attaching devices 23 pass in securing the spring member in position. The spring member 24; isprovided with a reduced central portion 27 and, a fingerpiece 28 which normally projects through and beyond the lower end of the casing 17 as shown in Figs. 2 and 3 ofthe drawing, and the finger piece 28 and the spring member 24, or that portion thereof which is lo cated within the casing 17 is provided with an aperture 29. v

I also employ a lock plate 30 whiclr is oblong and rectangular in form as is shown in detail in Fig. 7. The lower end portion of the plate 30 is fashioned to form an inwardly projecting lug 31 and the upper end portion of said plate is provided with an aperture 32 adapted to receive the shank 15 of the shade roller 12 as clearly shown in Figs. 2 and 3 of the drawing.

In the use of my improved lock device, as shown in Figs. 1 to 7 inclusive, the spring member 24 is first located upon the side member 11 of the window frame and the lock casing 17 placed thereon, after which the nails or screws 23. are passed through the ears22 and the apertures 26 of the head member 25 to secure the separate parts of the lock device in position, after which the lock plate 30 is placed within the chamber 20 of the casing 17 by passing the same downwardly through the upper end. of said casing and, in this operation, said plate is guided in its downward movement. by two inwardly directed, members 33bent inwardly from the side plates 19 of said casing,.as clearly shown in Figs. 3, 1 and 6 of .the drawing. It will be noted that in the downward movement of the lock plate 30 the P jecting lug 31 thereof will pass downwardly over the central portion 27 of the spring member 24 and into the aperture29, and be retained in a locked position by said spring member as is clearly illustrated in Fig. 3 of the drawing, and by forcing said spring member inwardly by a finger hearing upon the finger piece 28 thereof, the same may be released from the lug 31 to permit of the detachment of the lock plate 30 of the casing 17. It Will also be apparent that by forcing the finger piece 28 inwardly to rest upon theside member 11 of the window frame the lock plate 30 may be passed through the lower end portion of the casing 17, ifdesired.

1n the construction shown in Figs. -1 to 7 inclusive, the casing 17 and the spring memher 24: are independent of each other and are not intact prior to their mounting on a suitable support. In order to avoid this I may, if desired, secure said parts together when not in use by simply folding flaps, or the like 34 and 35 cut from the spring member 24 over the ears 22 of the casing 17 as shown in Fig. 8 of the drawing, all of the parts being apertured as indicated at 38 in said figure to permit of the passage of the screws, nails or the like 23 therethrough in securing the look device in position.

It will be understood that while I have shown my improved lock device mounted in connection with theshank at one end of the shade roller 12, I am not necessarily limited to this use, nor am I necessarily limited to the specific form and construction of the various parts of the lock device herein shown and described, and various changes in and modifications of the details of construction may be made, within the scope of the appended claims, without departing from the spirit of my invention or sacrificing its advantages.
